Abstract

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do an experiment to find out which products contain these harmful chemicals by researching the ingredients in different products. There are also potential links to methane produced by agriculture, burning of coal and wood, auto emissions, etc. (NCAR, 2006; NOAA, 2006; WMO, 2006)

Ask an Expert

The Ask an Expert Forum is intended to be a place where students can go to find answers to science questions that they have been unable to find using other resources. If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.

Climate Change Analyst

How is climate change affecting Earth? What will the changes mean for society? If these are questions that peak your curiosity, then you might be interested in a job as a climate change analyst. Climate change analysts evaluate climate data and research to determine how shifts in the climate will affect natural resources, animals, and civilizations. They use this information to make suggestions about what individuals and governments can do to ensure a higher-quality life for everyone in the face of a changing environment.

Environmental Scientist

Have you ever noticed that for people with asthma it can sometimes be especially hard to breathe in the middle of a busy city? One reason for this is the exhaust from vehicles. Cars, buses, and motorcycles add pollution to our air, which affects our health. But can pollution impact more than our health? Cutting down trees, or deforestation, can contribute to erosion, which carries off valuable topsoil. But can erosion alter more than the condition of the soil? How does an oil spill harm fish and aquatic plants? How does a population of animals interact with its environment? These are questions that environmental scientists study and try to find answers to. They conduct research or perform investigations to identify and eliminate the sources of pollution or hazards that damage either the environment or human and animal health. Environmental scientists are the stewards of our environment and are committed to keeping it safe for future generations.

Meteorologist

The atmosphere is a blanket of gases, surrounding Earth, that creates our weather. Meteorologists study the measurements and motion of the atmosphere, and changing events within it, so that they can predict the weather. This weather forecasting helps the general public and people who work in industries such as shipping, air transportation, agriculture, fishing, forestry, and water and power better plan for the weather, and reduce human and economic losses.
